| Discussion | Varieties 8 (8 in the flora). Pedicularis bracteosa is found in subalpine habitats across much of western North America, occurring throughout the Rocky Mountains from central British Columbia and Alberta to northern New Mexico, as well as the Coast Range south to northern California.

Pedicularis palustris and P. pennellii are extensively branched, with branching in P. pennellii more compact and subequal, making it appear shrubby. The branches of P. palustris, in contrast, become progressively shorter distally on the stem, giving the plant a pyramidal appearance. Calder and Taylor recognized subsp. insularis by its smaller or sometimes absent apical teeth on the galea margins. Boivin subsequently reduced it to a variety. Given this minor difference, this taxon (found only on Haida Gwaii [the Queen Charlotte Islands] of British Columbia) is not recognized here.
